HVAC (Heating, Ventilation, and Air Conditioning) equipment is a type of mechanical system that is used to regulate the temperature, humidity, and air quality of a space. It is used in both residential and commercial buildings to provide a comfortable and healthy environment for occupants. HVAC equipment is made up of several components, including a furnace, air conditioner, air handler, evaporator coil, and ductwork. The furnace is responsible for heating the air in the space, while the air conditioner cools it. The air handler is used to circulate the air, while the evaporator coil helps to remove moisture from the air. Finally, the ductwork is used to transport the air throughout the building. All of these components work together to provide a comfortable and healthy environment for occupants.
